Discrete Inputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
For each discrete input the following parameters can be configured separately:
•
type of action (NO/NC),
•
alarm class (control input, class 0, 1, 2 or 3),
•
tripping delay,
•
release delay,
•
enable conditions,
•
type of resetting, and
•
is the input used as a remote acknowledgment input.
Relay Outputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
For each relay output the following parameters can be configured separately:
•
type of action (NO/NC),
•
base status (during CAN bus failure),
•
is the relay 1 used as a readiness for operation relay (using this setting no other function can be assigned to
the relay) and
•
is a CAN bus failure is recorded via a relay. (Note: If you want to record time-critical alarms via a relay
please use the relays directly contained in the higher level control unit to eliminate delays caused by CAN
run-times.)
Configuration Options
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The following options exist for configuration. Configuration can be done alternatively via
•
the configuration plug using the direct configuration cable DPC and the PC program LeoPC1
•
the CAN bus using the D-1 unit
